LUTHER O'CROWELL, OF BROOKLYN, ASSIGNOR TO B. HOE & 00., OF NEW YORK, N. Y.

DELIVERY MECHANISM FOR WEB -PRINTENG PRESSES.

SPECIFICATION forming part of Letters Patent No. 301,0 dated June 24, 1884. Application filed June 22, 1883. (No model.)

To aZZ whom it may concern:

Be it known that I, LUTHER C. CROWELL, a citizen of the United States, residing in the city of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Delivery Mechanism for Web-Printing Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to that class of delivery mechanisms in which two or more webs or sections of a web are associated by transferring one or more of said webs or sections laterally, so as to bring it or them directly above orbeneath the other. In operating this class of machines considerable annoyance and delay has been occasioned by the time consumed in threading or conducting the leading ends of the webs or sections through the associating mechanism.

It is theobject of the present invention to provide means by which this annoyanceand delay may be avoided; and to that end the invention consists in providing the associating mechanism with means by which it is made self-threading, thus avoiding all delay and necessity for hand manipulation in introducing the webs or sections. The details in the construction and organization of the mechanism by which this is accomplished will be hereinafter so fully described and particularly pointed out that further preliminary description is deemed unnecessary.

In the accompanying drawings, Figure 1 is a plan view of a web-associating mechanism embodying the invention in a simple form. Figs. 2 and 3 are respectively front and rear elevations of the same, the web and certain of the tapes and pulleys being omitted in the latter,- and Fig. 4 is a longitudinal vertical section taken upon the line 00 w of Fig. 1, the frame-work being omitted.

Referring to said figures, it is to be understood that the web, after being. perfected by any ordinary form of printing mechanism, passes between the rolls 51 and into the control of the series of tapes 10 11, as shown in Figs. 1 and 4. The series of tapes 10 pass around the roll 51, and thence over a roll, 54.,

from which point one portion of the series passes around a roll, 53, and returns over tightening-pulleys 52, while the other portion passes downward around pulleys 64 and returns around the same tightening-pulleys. The series 11 pass around the roll 50 and return around the roll 54:. The web supported between the tapes 10 11 is carried to and over the roll 54, in passing which it is split into two sections, a b, by an ordinary slitter, 67,

after which the section a passes directly forward between the tapes 10 and another series of tapes or guides (not shown) to the rolls 53 55, while the section 1) passes to the associating apparatus,by which it is transferred laterally, so as to be brought directly beneath the section a, after which it is led to the rolls 53 55, between which rolls it passes directly beneath the section a, as shown in Fig. 1. From this point the two-ply web thus formed is conducted to and operated upon by any suitable delivery mechanism. The lateral transfer of the section b may be effected by any of the well-known forms of mechanism for that purpose. That shown in United States Letters Patent No. 265,556 has, however, been selected for the purpose of illustrating the principle of the invention. This mechanism consists of two parallel turning-bars, 66, arranged angularly across the path of the web,and at such a distance from each other that the web, by being led around both bars, will be transferred laterally the proper distance. In the present case the bars 65 66, instead of being arranged in a horizontal plane, as in the patent referred to, are arranged in a vertical plane, which arrangement is preferable in many cases, as it greatly reduces the space occupied by the apparatus.

As before stated, considerable annoyance and delay has been occasioned in operating associating mechanisms of this character, owing to the lack of any means for threading or conducting the leading end of the web or section to be transferred around the turning -bars. To obviate this difficulty, I provide the turning-bars with a threading-tape, 12, and companion cord 13, by which the leading end of the web or section to be transferred is con ductedfrom the roll 54 around the bars 65 66 tion 5, thence around the center of the bar 66,

thence laterally to and around the center of the bar 65, thence beneath a roll, 59, and

thence upward around a roll, 58, returning around tightening-pulleys 57 56. The companion cord 13 passes around a pulley, 60,10-

cated a short distance above the roll 54, thence downward around the bar 66 beneath the tape 12, thence around the bar 65 above said tape, thence around the roll 59 beneath said tape, thence past the roll 58 and around a pulley, 61,- thence downward around a pulley, 62, and thence laterally returning around a pulley, 63.

If preferred, the guides 15 may be omitted and the tape 12 passed around the roll .55.

The pulleys 56 57' 60 61 62 63 are mounted in adjustable hangers or brackets, so that their positions can be readily varied to regulate the tension of the tape and cord and their direction of travel with relation to the rolls 54 58 59 and the turningbars. The roll 59 and the pulleys over which the cord 13 passes are grooved, so as to hold the cord in the proper position, and "the bar 66 is provided with a groove, 9, for the same purpose, the bar 65 being provided with a wider groove, 8, for holding the tape 12 to its proper position upon the bar. The bars 65 66 are supported at one end in brackets 14, which are made adjustable, so as to vary the position of the bars to secure the proper transfer of the web.

The operation of the threading apparatusjust described isv as follows: As the leading ends of the two narrow webs or the two sections of the wide web pass above the roll 54,

one will be conducted directly to the rolls 53 55, as already set forth,while the other will be turned downward by the tapes 10 and caused to enter the-bite of l the tape 12 and cord 13, between which it will be carried around the bars 66 65 and roll 59, from which point it will be carried upward to the roll 58 and be projected between the guides 15, so as to be presented to the rolls 53 55 beneath the other Web or section, thus making the apparatus self-threading. If more than one web or section is to be transferred laterally, each pair of turning-bars will be provided with a threading. apparatus similarly arranged, and if a different form of transferring apparatus is used the arrangement of the threading tape and cord can be readily, changed to correspond.

. Although a single tape and cord arranged as shown will usually be found sufficient to conduct the leading end of the web or section through the transferring apparatus,it will readily be seen that two or more such tapes and cords can be provided if one is found insuffi-. cient, and it will also be seen that anarrow tape can be used in place of the cord 13, if preferred.

What I claim is a 1. The combination,with means for advancing two webs or sections side by side, of means for transferring laterally one of said webs or sections to associate it with the other, and means for automatically conducting the leading end of said transferred web through the transferring mechanism, all substantially as described.

2. The combination,with means for advancing two webs or sections side by side, of turning-bars arranged-to transfer laterally one of said webs or sections to associate it with the other, and tapes, ora tape and cord, as 12 13, arranged to conduct the leading end of said transferred web or section around said bars, all substantially as described.

3. The con1bination,with means for advancing two webs or sections side by side, of turning-bars arranged to transfer laterally one of said webs or sections to associate it with the other, said bars being provided with grooves,

as 8 9, and tapes, or a tape and cord, as 12 13,
